Answer:

x = 9

Step-by-step explanation:

You would set the problem up as:

13x + 2 + 3x - 4 + 5x - 7 = 180

Combine like terms then solve using algebra

This will give you x = 9

Hope this helps!!

Angles in a triangle add up to 180 degrees

The value of x is 9

The angles are given as:

[tex]\mathbf{Angles = 13x + 2, 3x - 4 , 5x - 7}[/tex]

By the sum of angles in a triangle, we have:

[tex]\mathbf{13x + 2+ 3x - 4 + 5x - 7 = 180}[/tex]

Collect like terms

[tex]\mathbf{13x + 3x + 5x = 180 + 7 + 4 - 2}[/tex]

[tex]\mathbf{21x = 189}[/tex]

Divide through by 21

[tex]\mathbf{x = 9}[/tex]

Hence, the value of x is 9
